+Traffic Dump Plugin
+*******************
+
+Description
+===========
+
+``Traffic Dump`` captures session traffic and writes to a replay file
:ts:git:`tests/tools/traffic-replay/replay_schema.json` for each captured
session. It then can be used to replay traffic for testing purpose.
+
+Plugin Configuration
+====================
+.. program:: traffic_dump.so
+
+* ``Traffic Dump`` is a global plugin and is configured via
:file:`plugin.config`.
+ .. option:: --logdir <path_to_dump>
+ (`required`, default:empty/unused) - specifies the directory for writing
all dump files. If path is relative, it is relative to the Traffic Server
directory. The plugin will use first three characters of client ip to create
subdirs in an attempt to spread dumps evenly and avoid too many files in a
single directory.
+
+ .. option:: --sample <N>
+ (`optional`, default:1000) - specifies the sampling ratio N. Traffic Dump
will capture every one out of N sessions. This ratio can also be changed via
traffic_ctl without restarting ATS.
+
+* ``traffic_ctl`` command.
+ ``traffic_ctl plugin msg traffic_dump.sample N`` - changes the sampling
ratio N as mentioned above.
+
+Replay Format
+=============
+This format contains traffic data including:
+* Each session and transactions in the session.
+* Timestamps.
+* The four headers (ua request, proxy request, origin server response, proxy
response).
+* The protocol stack for the user agent.
+* The transaction count for the outbound session.
+* The content block sizes.
+* See schema here: :ts:git:`tests/tools/traffic-replay/replay_schema.json`
